Log in issue

Hi, I may be stupid asking this but I can find the solution, in the theme that I have now I haven’t been able to find the log in button and I don’t want to change it. Every time that I get to the blog is a mess trying to see how to log in, usually I have to go clicking other things for the screen pop up the user log in, is there another way? I want to see it in the side bar in my blog, is this possible?
